Add tests/test-committer This checks to see if the EMAIL environment variable is being used for commit.

Use application/octet-stream as the content-type of unknown binary files

remove appendfile data as soon as not needed.

Make bundlerepo use proper index format for revlogng bundlerepo just appends index entries from the bundle onto the index for the current repo. This patch makes sure it appends the correct format.

Fix hg qdiff <file>

Ignore EPIPE in pipefilter This hides the following traceback (there's a race condition involved, so you may have to try a few times to hit it): $ hg sign --key key-that-does-not-exist Signing 2062:4bad92f4ea65 gpg: skipped "key-that-does-not-exist": secret key not available gpg: signing failed: secret key not available Exception in thread Thread-1: Traceback (most recent call last): File "threading.py", line 442, in __bootstrap self.run() File "threading.py", line 422, in run self.__target(*self.__args, **self.__kwargs) File "mercurial/util.py", line 24, in writer pin.close() IOError: [Errno 32] Broken pipe abort: Error while signing

Don't send "Content-Type: none" mimetypes.guess_type will return (None, None) when it can't detect the filetype.

Fix filerevision-raw.tmpl Two bugs: - conteXt-type instead of conteNt-type - trailing newline The easiest way to fix the second one (and keep it fixed) is to put everything inline in map-raw.

convert-repo: fix reversed time zone offset

catch SIGBREAK on windows.

update windows readme to document msys/mingw rxvt problems.

fix util.canonpath on windows. old test for absolute path was not portable. use os.path api instead.

make appendfile simpler so it does not break with revlogng on windows. it used to cache open files. this made revlogng break because it wants to rename files when splitting .i into .i/.d, but cannot rename or unlink open files on windows. new code is bit slower, but safe on linux and windows. proper fix for too many open/close of changelog/manifest belongs in different place. can get 10% speed improvement back.

Exit test-hup only after the background process has died. Otherwise the open file might let the tests fail on NFS.

merge revlogng with mpm tip

Fix transaction handling during interleaved file split.

merge 0.8.1 with revlogng

Additional appendfile fixes for interleaved data/index files The appendfile code was not passing default version info to the changelog or manifest classes, and so they were always being created as version 0. revlog.checkinlinesize had to be corrected to seek to the end of the index file when no index file was passed (only clone does this)

Speedup revlog.ancestors for the linear case revlog.ancestors can be expensive on big repos. This cuts down the overall time for hg update by ~19% by short cutting revlog.ancestors when one of the revisions is reachable from another.

Reduce index memory usage by storing the bare string instead of tuples Storing the tuple returned by struct.unpack significantly increases the memory required to store the entire index in ram. This patch uses struct.unpack on demand instead.

New lazy index code for revlogs. This tunes for large repositories. It does not read the whole index file in one big chunk, but tries to buffer reads in more reasonable chunks instead. Search speeds are improved in two ways. When trying to find a specific sha hash, it searches from the end of the file backward. More recent entries are more likely to be relevant, especially the tip. Also, this can load only the mapping of nodes to revlog index number. Loading the map uses less cpu (no struct.unpack) and much less memory than loading both the map and the index. This cuts down the time for hg tip on the 80,000 changeset kernel repo from 1.8s to 3.69s. Most commands the pull a single rev out of a big index get roughly the same benefit. Commands that read the whole index are not slower.

Fill in the uncompressed size during revlog.addgroup This uses code from Matt to calculate the size change that would result from applying a delta to keep an accurate running total of the text size during revlog.addgroup
